' specication.

This invention relates to that class of vehiele wheel rims in which a tire-carrying rim capable of carrymg an mdated tire 1s detachably secured to a vehicle wheel. Rims of this class are commonly called demountable rims.

The present invention relates to lmproved means for securing a detachable tire-carrying rim u-pon a Wheel.

It also contemplates certain improvements in the structure of the tire-carrying run .serving to insure the proper seating of the same upon the wheel. A

Vmy invention is capable of many other embodiments. j

Referring to the drawings in detail, the

numeral 1 designates a wheel felly, to which is permanently secured, by shrinking or otherwise, the felly band 2. This felly band is preferably provided at one edge with an outwardly projectingflange 3 provided with a rim-engaging face 4, and atthe other edge Evith an inwardly or downwardly inclined ace 5.

In Figs. l, 2', 4 andl5 l have shown a detachable tire-carrying rim 6 provided with a pair of flanges 7 and 8 having similarly inclined wedging surfaces 9 and 10 adapted to engage, respectively, with the wedgingl surfaces 4 and 5 on the felly band. In order to promote a uniform engagement between these wedging surfaces, to permit of the use of dierent tire-carrying rims interchangeably upon the same wheel and to make it possible to force tire-carrying rims of slightly different dimensions to the same lateral position upon the wheel, l provide the wedging faces of the flanges 7 and 8 with circumferentally spaced projections or lands l1. By the use of these lands the rim may actually be supported only at intervals, although usually the bearing surfaces of the rim and felly band will engage throughout a greater or less portion of the space between adjacent lands. In case the rim is slightly under-size, it will straighten out between adjacent lands, thus, in effect, enlarging its diameter and permitting it to be forced laterally uponthe wheel to the desired extent.

As it is impracticable in the manufacture of rims upona commercial scale to insure absolute uniformity of dimensions unless same lateral `position upon the wheel. A ny be placed opposite to'each other, as shown.

in Fig. 3, or may be otherwise suitably located. It is not necessary to have the same number of lands upon the two faces, though this is preferable. The lands or projections may be of any suitable height, preferably about one-thirty-second of an inch, though I do not desire to limit myself in any way to this dimension. The lands may be formed integral with the flanges or firmly secured thereto in any suitable manner. I do not claim the use of lands broadly in this application, as the same forms the subject-matter of'my applicationV Serial Number 614,356

filed of even date herewith. In 'this application' I claimff merely the specific modification of the invention claimed in theabove-named application, in which the lands are formed upon the inner or under surface of the tire' carrying rima In Figs. 1r, 4', 5, -8 and 9 I have shown an improved locking-means "for securing the tire-carrying rim upon the wheel. These means comprise a plurality of locking-members 12 adapted to be moved into engagement with the flange 8 of the tire-carrying rim, wed'ging the latter upon the wheel and securing it in position thereon. These locking-members'12 comprise wings 13 adapted to engage the rim, and body or sleeve portions 14 internally threaded and secured` upon the threaded portions 15 of the nuts 16. The nuts are provided with heads 17 and are internally threaded, as indicated at 18. These nuts screw on threaded inwardly inclined extensions 19 formed on the bolts 20, which pass through holes in the felly. The bolts are provided between the shanks thereof and the threaded extensions 19 with collars 21. Nuts 22 are used to prevent the withdrawal of the bolts. The collars 21 have the function of bolt-heads and are clamped against the face of the felly or against the washers or guide-plates 23, the purpose of which will be explained. The threads on the bolt extensions'19 and on the outside of the nuts 16 are of opposite pitch, so that the rotation of the nuts 16 will cause them to move in one direction or the other upon-thebolt extensions. The sleeves 14, if held from rotation while the nuts are turned, will at the same time move along the nuts in the same direction in which the nuts themselves are moving, so that these sleeves will move at twice the speed at which the nuts move. These sleeves are prevented from rotationwhen the nuts are turned by reason offthe engagement of the wings 13 with the inclined wedging-face 5. When the members 12 are withdrawn, as shown in Fig. 5, the tire-carrying rim will pass freely thereover and may be removed, but when the members are moved into the position shown in Fig. 4, the rim will be positively locked in position in an obvious manner. In order to guide the wings 13 when the lockingmembers are fully withdrawn, as shown in Fig. 5,'I provide the guide-plates or washers 23, which are provided with the flanges 14, preferably bent from their upper edges.

In the normal operation of the rim, the sleeves 14 engage the heads 17 of the nuts 16 before the wings 13 leave the flanges 24, as shown in Fig. 5, thereby limiting the outward movement of the locking-members. The inward movement of the locking-members is limited by the engagement of the inner faces of thenuts .16 with the flanges 21, as shown in Fig. 4. The limits of movement of the locking-members may be adjusted by regulating the initial positions of of the locking-members upon the nuts. This may be accomplished by removing the nuts 22 and withdrawing the bolts 20 sufficiently to permit the wings 13 to disengage the -flanges 24, when the locking-members may be rotated about the nuts 16 and screwed one or more turns in either direction thereon. l

In Figs. 6, 7 and 10 I have shown a modified form of my improved locking means, as adapted to a slightly modified form of the tire-carrying rim. The tirecarrying rim 30, shown in these figures, is-

provided at one side with a supporting flange 31 engaging an outwardly inclined.

felly band. For forcing the wedging ringbetween the inclined faces 33 and 5, I utilize the locking-devices 36, similar to the Y locking-device 12 previously described. These devices 36 screw upon the nuts 16, which in turn screw upon the extensions V19 of bolts 20, asalready fully set forth. In order to guide the locking-devices 36 and prevent their rotation when withdrawn sufficiently to permit the free removal of the tire-carrying dicated in Fig. 7, I-.provide the blocks 37 secured to the face of the felly by means of the flanges 21 of the bolts 20.- The upper faces 38 of these blocks are inclined and form, practically, extensions of the inclined face 5. The blocks are preferably additionally secured to the face of the felly rim and wedging ring, as infirmly held a alnst rotation.

manana by means of screws adapted toy pass through the screw-holes 39, these screws serving to prevent turning of the blocks'upon the face of the felly. The blocks are preferably provided with recesses 40 of angular o utline, adapted to receive the collars 21, whlch are similarly shaped. The bolts are thus rll`he initial positions of t e locking-members 36 may be adjusted by withdrawing the bolts 20 in the manner already fully described.

Having thus described my invention, ll
